I consider the first band that gets engraved by the rifling to be the front driving band.
Obviously on some designs it is smaller than others.

I agree that the first portion that is engraved is the "driving" band. I shoot a lot of Verals LFN and WFN designs and they have a large driving band.
If you are going to make a hole in something. MAKE IT A BIG ONE!
It is important to consider the firearm for which the bullet was designed. The Ranch Dog bullets are designed for Marlin leverguns which are famous for very little if any throat in front of the chamber. The Keith bullets are designed for revolvers which have long throats in the charge holes.

it's the band forward of the crimp groove, in your second photo

The term "front driving band" is meaningless in a bullet and application where it performs no particular function. Your first picture the "band" in front of the first lube groove seems to not be prominent nor have any features to make it significant. That first bullet, I don't know the application, but I might not fill all the grooves with lube, and I might not crimp in the first groove. It will depend on the throat of the firearm I use it in.

The purpose is, I want to make sure I have the correct terminology for all the bullet parts for my bullet cataloging webapp.
Thanks for all the responces.

Look at the photo. There is a sized "BAND" In front of the crimp groove. It is a circular sized area, surface, portion in of the crimp groove therefore a band of sized area.
I think it is simple.
Am I wrong?
BTW, it could be called a sized portion of the nose of the bullet, or just the nose of the bullet, or the portion in front of the crimp groove.
But the sized portion caused a band or circular area in front of the crimp groove.
So to me it is a band of sized area in front of the crimp groove.
Am I wrong????

So based on this, this NOE boolit is a better choice for the Marlin that a "bore rider"?Attachment 315013[ATTACH
IT AINT what ya shoot--its how ya shoot it. NONE of us are as smart as ALL of us! The more I travel, the more I like right where I am.
FWIW: I've always heard/used the term "Driving Band" associated with the Rear band -- that experiences the driving pressure
and the Front band (if any/as in Keith SWC) as the "Cleaning Band" -- hold-over from BP cartridge shooting
Historically, as used in many writings, it is the front band that is the "drive" band.

Looking at the nomenclature again -- especially as it plays against artillery /mortar/and cast-grooved projectiles, it would appear
that all the parallel shank bands are considered the "driving" bands which engage the rifling under pressure.
That I could understand. But calling the front band "the" driving band doesn't pass the makes-sense test.
Am I missing something here?
Yes, you are misconstruing me intended meaning of "the" incorrectly when it is used in "the front drive band". The "the" used only differentiates it as the drive band which is in front of the other drive bands. All of the bands are drive bands. "Drive" is only an adjective, not an adverb, in its use as referring to that band. The term "front" isn't giving that band some distinction to "drive" anything. "The" as used, is not an adverb. Some may give speculation on what the intended purpose of a specific front drive band design may be, but it is still "the front drive band" simply because it is front of the other drive bands because all those bands that fall behind it, including the base drive band are all drive bands).

Could the front band be called a helper band?
Could the front band be called a steering band as it steers the following band, bands into the barrel?
Could the front band be called a band with no description other than a band?
Could the front band be called one band of two or more?
Could the front band be called the leading band followed by the following band or bands?
Could the front band be called a part of the bullet?
What are some more possibilities of the name of that raised circular area of that thing on a bullet
Let see some of them?
